SPECIFICATION forming part of Letters Patent No. 570,453, dated November3, 1896.

Application filed August 22, 1895. Serial No. 560,116. (No model.)

To all whom it m/cty concern:

Be it known that I, LOUIS K. COE, a citizen of the United States,residing at Saginaw, in the county of Saginaw and State of Michigan,have invented certain new and useful Improvements in Type-Writers; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

My invention is an improved paper-carriage for type-writers, its objectbeing to eliminate the shifting mechanism, automatically supply thepaper, and make visible writin g. This I obtain by the mechanismillustrated in the accompanying drawings, of which Figure 1 is asectionalview. Fig. 2 is apart of the same view enlarged, showing theparts in different positions. Fig. 3 is an elevation of the right endfront. Fig. 4, is a vertical section through the cylinder on line X X ofFig. 1. Fig. 5 is an elevation of the righthand end. Fig. 6 is a sectionon line Y Y of Fig. 1. Fig. '7 is a view of the left-hand end of thecylinder. Fig. Sis a front elevation of the same, and Fig. 9 a sectionof the cylinder and bobbin B In the drawings, S is a shaft journaled inthe type-writer frame A and has a spiral groove SG, commencing at itsleft hand and extending to the middle of the shaft, and having upon theother half of the shaft the peculiarly-formed groove SE, which, co1nmencing on the right hand of the shaft, passes nearly around it in avertical plane, then slants to the left at an oblique angle for a cer:tain distance, then around the shaft parallel to the first groove to apoint on a line with the commencement of the slant SE, then slants againto the left parallel with the first slant and in the same horizontalplane, and so on toward the middle of the shaft, forming a continuousgroove having a slant to the left at regular distances, the slants allbeing upon the same side and parallel and in the same plane.

0 is a hollow cylinder having hearing at each end upon the shaft S, theright-hand bearing 0 projecting three-eighths of an inch from thecylinder and the left'hand bearing 0 projecting three-sixteenths of aninch from the cylinder, or in that proportion. The righthand bearingforms a collar carrying the handle-barL and large pinion P The outer endof the collar C has an annular rib R, provided with ratchet-teeth, asshown in Fig. 5. The large pinion P has a projection P from its bearingP to which is pivoted the dog or pawl P, having an extended end P,adapted to engage the ratchet-teeth of the rib B.

To the bearing P of the pinion I are pivoted the arms L of the rod L,which has a depending arm. By moving this depending arm to the right orleft the pinion P may be made to slide correspondingly on thecollar C Sis a pawl pivoted in a slot in the collar (3 so as to engage and enterthe groove SE and follow it as the collar is revolved.

S is a spring underneath the outer end of the pawl for the purpose ofkeeping it in position in the groove.

The outer end S of the pawl S is beveled to the left. This pawl islocated atsuch a point in the collar 0 that when the pawl P is inengagement with the ratchet-wheel R the pawl S is in its groove SE, butwhen the pawl P is drawn out of engagement with its ratchet-wheel R, asit will be when the depending arm of the rod L is moved to the right,thereby moving the large pinion P on the collar (3 to the left, thelarge pinion P will slide upon the beveled end S of the pawl S and forceit, S out of the groove SE, as will be hereinafter mentioned.

The cylinder 0, as previously mentioned, is loosely journaled on theshaft S. Across the longitudinal surface of the cylinder 0 is a slot SCabout one-fourth of an inch wide. WVithin the cylinder and just at theedges of this slot are two steel rollers R and R which maybe about threethirty-seconds of an inch in diameter, and pressing against the underside of these rollers is a large rubber roller R all being journaled inthe ends of the cylinder, with the shaft of the roller H extendingthrough the right-hand end of the cylinder and having upon its outer endoutside of the cylinder a pinion 1, adapted to mesh into the largepinion P when the same is moved to the left on the collar 0 so that whenthe pinion P is in the position just described and the cylinder isrevolved by the means hereinafter described the pinion l on the end ofthe roller R will run around upon P as the cylinder is revolved and thusrevolve the roller R Just back of the roller R and a little to one sideis a bobbin R upon which is wound the paper used in writing. This paperis a continuous sheet and may be provided with perforations transverselydividing it into the usual sheets of paper used in type-writing. Theymay be, of course, of any length, and it is understood that the papermust be manufactu red expressly for use in this style of a type-writercarriage and that the bobbin must be wound with this paper beforeplacing it in the cylinder.

When first placed in the cylinder, the sheet is drawn out by and betweenthe rollers R and R and extends around the cylinder and into the slot SCand between the rollers R and R S is a spring within the cylinder on theleft side thereof adapted to enter the spiral groove SG and move throughit as the cylinder is revolved, which action, it will be observed, willdraw the spring to the position shown in the dotted lines in Fig. 1. henthe pawl S in traveling through the groove SE, has reached the slantingpart of the groove, the spring S will force the cylinder 0 along theshaft S to the right, the pawl S traveling in the sliding groove untilit has reached the end of the slant, which will check the movement ofthe cylinder along the shaft S, the spring S at the same time havingbeen relieved of its tension.

L is a handle-bar, connected at the rear of the machine at T to thespacing-bar T, connected to the keyboard in the common way. The rod L isconnected to the handle-bar L through the lug L on the handle -bar L Thehandle-bar L rocks loosely on the collar 0, the collar serving as apivot for the bar, as shown in Figs. 1, 2, and 5.

Depressing the spacing bar tips the rear end of the handle-bar L andwith it the rod L, which it carries, thereby turning the large pinion Pengaged by the arms L and thus pushing the pawl P upon the ratchet-wheelR and turning it over one tooth, which, it will be observed, also turnsthe cylinder C.

Releasing the spacing-bar allows the pinion P to go back, carrying withit the pawl P, which will then engage the next tooth of theratchet-wheel B. At each depression of the spacing'bar the handle L willbe rocked, which communicates motion to the cylinder, as just described,through the ratchet and pawl R P, which movement, being the space of oneratchet-tooth at a time, is adapted to give the required space for theletters, the spacing-bar being depressed as each letter of the keyboardis struck, as in the ordinary typewriter-carriage.

The pawl S moving in the groove S, guides the cylinder 0, as previouslystated, in re volving, and when the pawl S has reached the slantinggroove SE the spring S forces the cylinder to the right, as heretoforedescribed, the length of the slant SE being the distance desired betweenthe lines of the writing upon the outside of the cylinder. It will thusbe seen that the letters are spaced automatically and that a newline ispresented when the cylinder has completed one revolution, and that thewritten line will extend around the cylinder instead of across itlongitudinally, as is common. \Vhen the cylinder 0 has thus revolved andmoved to the right regularly, and the pawl S has reached the right endof the shaft S, the blank sheet will have been filled with writing.

To remove the written sheet and obtain a blank sheet, the operatorpresses the depending arm of the rod L to the right, which, aspreviously described, forces the large pinion P to the left and intomesh with a smaller pinion P on the end of the roller R thereby drawingthe pawl S out of the groove SE and the pawl P out of the ratchet-teethof the wheel R. Then the operator pushes the cylinder C to the leftalong the shaft S, which, by reason of the spring S running in thespiral groove SG, causes the cylinder 0 to revolve, and the revolving ofthe cylinder revolves the roller R within the cylinder for the reasonthat the pinion P in mesh with the pinion P which is held againstrotation by the arms U of the rod L, is carried around the pinion P bythe revolution of the cylinder, thus revolving the roller it Therevolution of the roller unwinds the paper from the bobbin R and pushesit out between the rollers R and R and draws it in between the rollers Rand R which draws the written sheet within the cylinder.

An empty bobbin B may be placed within the cylinder for the purpose ofwinding the paper upon it after it has been written. The bobbins R and Rare placed within the cylinder by passing them through the holes 1 l inthe end of the cylinder, with their inner ends in bearings in theopposite end of the cylinder.

at 4 are bars placed across the openings 1 1 and rest in the'sockets 3and 5 on the end of the cylinder. These bars are each provided with abearing 2 for the left-hand end of the bobbins and R"; The bobbin R hasa central shaft 6, carrying within the bobbin the coiled spring 7, oneend of the spring secured to the shaft 6, the other to the wall of thebobbin, and when placed within the cylinder and the written paper passedover it the tension of the spring 7 will cause the bobbin to revolvejust enough to take up the slack of the paper between the roller R and Rand, as the typewriter is run, to continue to wind the paper passedbetween these rollers upon the bobbin.

Having thus described my invention, what I'claim as new, and desire tosecure by Letters Patent, is-- 1.
